When I was considering sending my bag back to Alexander Wang for repair, I couldn't find any threads from TPF'ers who had gone through the process.... Hopefully, my experience will be helpful.
My Brenda bag tore along the zipper after only carrying it a few times. The boutique where I purchased it was out of state and I didn't want to mail it back to them and my seamstress and shoemaker could not fix it. I called AW and they were nasty about the return, but finally said to mail it back along with a copy of my receipt and a letter detailing the repair. I was nervous just sending it off, but today, 6 weeks later received my bag back as good as new. I'm glad it all worked out and I can start enjoying my Brenda!

Did you take before/after pics, perchance? It's so sad that AW bags have various quality issues (not just limited to one style either). 
*knock on wood* for my 2 roccos.
